Kusukela ngo-2022, isidingo semakethe semikhiqizo yokugcina amandla sikhule kakhulu ngenxa yokushoda kwamandla kanye nezintengo zikagesi ezikhuphukayo emazweni amaningi emhlabeni jikelele.Ngenxa yokushaja okuphezulu nokusebenza kahle kokukhipha kanye nokuzinza okuhle,amabhethri e-lithiumemhlabeni jikelele zithathwa njengezokuqala ezikhethwa yimishini yesimanje yokugcina amandla.Esigabeni esisha sokuthuthukiswa, kuwumsebenzi obalulekile kubo bonke ozakwethu embonini ye-copper foil ukuthi baqhubekele phambili futhi baqhubekisele phambili ukukhuthaza ukuguqulwa komkhiqizo kanye nokuthuthukiswa ukuze kuhlangatshezwane nesidingo semakethe entsha futhi kuzuzwe ukuthuthukiswa kwekhwalithi ephezulu.Akunzima ukuthola ukuthi imakethe yebhethri ye-lithium yanamuhla iphumelela kakhulu, isidingo sokugcinwa kwamandla sikhula ngokushesha, umkhuba wokunciphisa ibhethri uvamile, futhi imikhiqizo yebhethri ye-lithium ye-copper encane isiphenduke "imikhiqizo yeziqhumane" yezwe lethu.
I-lithium copper foil isifinyezo salokhuibhethri ye-lithium-ioni-copper foil, esetshenziswa njengempahla yomqoqi we-anode wamabhethri e-lithium-ion futhi ingeyesigaba esibalulekile se-electrolytic copper foil.Iwuhlobo lwe-metallic copper foil ekhiqizwa indlela ye-electrolytic enokwelashwa okungaphezulu, futhi iwuhlelo oluvame kakhulu lwefoil yebhethri ye-lithium yethusi.Ucwecwe lwethusi lwebhethri ye-Li-ion lungahlukaniswa ngokuqina lube ucwecwe lwethusi oluncane (ama-microns angu-12-18), ucwecwe lwethusi oluncane kakhulu (ama-microns angu-6-12) kanye nocwecwe lwethusi oluncane kakhulu (ama-microns angu-6 nangaphansi).Ngenxa yezidingo eziphezulu zokuminyana kwamandla ezimoto zamandla amasha, amabhethri kagesi ajwayele ukusebenzisa i-ultra-copper nencane kakhulu ifoyili yethusi enogqinsi oluncane.
Ikakhulukazi foramandla amabhethri e-lithiumngezidingo eziphezulu zokuminyana kwamandla, ucwecwe lwe-lithium yethusi lube ngenye yempumelelo.Ngaphansi kwesisekelo sokuthi ezinye izinhlelo zihlala zingashintshiwe, ucwecwe lwekhopha olusetshenziswa kumabhethri e-lithium luba mncane futhi lube lula, kwandisa ukuminyana kwamandla amakhulu.Njengomthombo ophakathi nendawo we-lithium yethusi ochungechungeni lwezimboni, ukuthuthukiswa kwemboni kuthonywa izinto zokusetshenziswa ezikhuphukayo kanye namabhethri e-lithium angezansi.Izinto zokusetshenziswa ezikhuphuka nomfula njengethusi ne-sulfuric acid ziyizimpahla eziyinqwaba ezinokutholakala okwanele kodwa ukuguquguquka kwentengo okuvamile;amabhethri e-lithium aphansi athonywa ukuthuthukiswa kwezimoto zamandla amasha kanye nokugcinwa kwamandla.Esikhathini esizayo, izimoto zamandla amasha ziyazuza kuhlelo lukazwelonke lwe-carbon neutral, futhi izinga lokuthandwa kulindeleke ukuthi liqhubeke landa kakhulu, futhi isidingo samabhethri e-lithium-ion amandla sizokhula ngokushesha.Isitoreji samandla amakhemikhali aseShayina sikhula ngokushesha, futhi ngokuthuthukiswa kwamandla omoya, i-photovoltaic nezinye izimboni, isitoreji samandla e-electrochemical yaseChina sizokhula ngokushesha.Izinga lokukhula elihlanganisiwe lomthamo wokugcinwa kwamandla we-electrochemical ofakiwe kulindeleke ukuthi libe ngu-57.4% kusukela ngo-2021-2025.
Ngemizamo ehlanganyelwe yezinkampani zamabhethri nabakhiqizi be-foil yethusi, i-lithium yebhethri ye-copper foil yaseChina ihamba phambili emhlabeni mayelana nokukhanya nobuncane.Njengamanje, i-foil yethusi yamabhethri e-lithium yasekhaya ikakhulukazi ama-microns angu-6 nama-microns angu-8.Ukuze kuthuthukiswe ukuminyana kwamandla ebhethri, ngaphezu kokuqina, amandla aqinile, ukunwebeka, ukumelana nokushisa nokumelana nokugqwala nakho kuyizinkomba zobuchwepheshe ezibalulekile.Ama-microns angu-6 kanye ne-foil yethusi ezacile kakhulu sekugxilwe kusakhiwo sabakhiqizi abajwayelekile basekhaya, futhi njengamanje, ama-microns angu-4, ama-microns angu-4.5 kanye neminye imikhiqizo emincane esetshenzisiwe emabhizinisini amakhulu njenge-Ningde Time kanye ne-China Innovation Aviation.
Okukhiphayo kwangempela kunzima ukufinyelela amandla okuzisholo, futhi izinga lokusebenzisa umthamo jikelele wemboni ye-lithium ye-copper foil cishe i-80%, kucatshangelwa umthamo ongavumelekile ongakwazi ukukhiqizwa ngobuningi.6 micron ucwecwe lwethusi noma ngaphansi ujabulela amandla aphezulu okuxoxisana kanye nenzuzo ephezulu ngenxa yobunzima bokukhiqiza.Uma kucatshangelwa imodeli yentengo yentengo yethusi + imali yokucubungula yefoyili yethusi ye-lithium, imali yokucubungula yefoyili yethusi engu-6 micron ingu-5.2 million yuan/ton (kuhlanganise nentela), engaphezulu ngo-47% kunemali yokucubungula yefoyili yethusi engu-8 micron.
Izuza ekuthuthukisweni okusheshayo kwezimoto zamandla ezintsha zaseChina kanye nemboni yebhethri ye-lithium, i-China ingumholi womhlaba wonke ekuthuthukisweni kwe-lithium yethusi ecwecwe, emboza ucwecwe lwethusi oluncane, ucwecwe lwethusi oluncane kakhulu kanye necwecwe lethusi elincanyana kakhulu.I-China isibe ngumkhiqizi omkhulu kakhulu emhlabeni we-lithium copper foil.Ngokusho kwe-CCFA, amandla okukhiqiza i-lithium yethusi ye-lithium azoba amathani angama-229,000 ngo-2020, futhi silinganisela ukuthi ingxenye yemakethe yaseChina kumthamo wokukhiqiza we-lithium yethusi womhlaba wonke izoba cishe ngama-65%.
Isabelo se-Nordic: umholi we-lithium copper foil uqale kabusha ukukhula, obambe iqhaza kakhulu ekuthuthukisweni, ekukhiqizeni nasekudayiseni ucwecwe lwethusi lwe-electrolytic lwamabhethri e-lithium-ion, imikhiqizo eyinhloko ye-electrolytic yethusi ye-copper ihlanganisa i-4-6 micron encane kakhulu ye-lithium yethusi ucwecwe, 8-10 micron Icwecwe le-lithium yethusi elincanyana kakhulu, ucwecwe lwethusi lwe-lithium micron olusebenza kahle kakhulu oluyi-9-70 micron, ucwecwe lwethusi oluyi-105-500 micron ultra-thick electrolytic, njll., kwasekhaya ukuzuza kuqala u-4.5 micron kanye nama-micron angu-4 ezacile ngokwedlulele ucwecwe lwethusi lwe-lithium ukukhiqizwa ngobuningi.
I-Jiayuan Technology: Ukuzibandakanya ngokujulile ku-lithium yethusi ucwecwe, umthamo wokukhiqiza esizayo uyaqhubeka nokukhula, ikakhulukazi uhileleke ekukhiqizeni nasekuthengisweni kwezinhlobo ezahlukene ze-foil yethusi ye-electrolytic esebenza kahle kakhulu yamabhethri e-lithium-ion asuka ku-4.5 kuya ku-12μm, asetshenziswa kakhulu ku-lithium-ion. amabhethri, kodwa futhi nenani elincane lezinhlelo zokusebenza ku-PCB.Le nkampani isungule ubudlelwano besikhathi eside nabakhiqizi abakhulu basekhaya bebhethri ye-lithium-ion futhi ibe umphakeli oyinhloko we-lithium yethusi ecwecwe.Le nkampani ibambe iqhaza ngokujulile kucwecwe lwethusi lwe-lithium futhi ibilokhu ihola ocwaningweni nasekuthuthukisweni komkhiqizo, futhi manje isinikeze ama-micron angu-4.5 amancane kakhulu we-lithium copper foil kumakhasimende ngeqoqo.
Ngokusho kwamaphrojekthi ezinkampani ezinkulu ze-copper foil kanye nenqubekelaphambili yomthamo wazo wokukhiqiza, iphethini yokunikezwa okuqinile kwe-copper foil ingase iqhubeke ngo-2022 ngaphansi kokukhula okusheshayo kwesidingo, futhi imali yokucubungula i-lithium yethusi ucwecwe kulindeleke ukuba igcine iphezulu. izinga.U-2023 uzobona ukuthuthuka okukhulu ohlangothini lokuhlinzeka, futhi imboni izophinde ilinganise kancane kancane.
